1. INTRODUCTION
by Robert D. Drennan
During the past four years the Palo Blanco Project has conducted
fieldwork in and around the Tehuacan Valley with the objective of contribu
ting to a better understanding of the processes of social, political, and
economic development by which complex societies emerge. To this end we
have focussed on the Late and Terminal Formative and Early Classic periods.
In terms of the ceramic chronology established by MacNeish, Peterson, and
Flannery (1970), these include the Late Santa Maria and the Early and Late
Palo Blanco phases (Fig. 1.1). Before this time the fehllacan Valley was the
scene of a series of relatively autonomous, egalitarian farming villages.
At the beginning of the period we study, a primitive Central place was
11 11
founded and became the geographical focus of a society which included a
number of villages subsidiary to the central place. During the Early Palo
Blanco phase this pattern crystalized and spread throughout the Tehuacan
Valley, with the result that some half-dozen polities, each focussed on a
central place of moderate size, divided the valley among themselves. No one
of these polities seems ever to have dominated the entire valley, although
competition among them and consequent waxing and waning of various centers
are apparent.
It is this process of sociopolitical change we seek to understand
in terms of the region in which it developed and in terms of its relation
ship to the sociopolitical developments apparent in the nearby and contem
poraneous but much more spectacular centers of Teotihuacan and Monte Alban.
Our preliminary reconstruction of the sociopolitical development in the
Tehuacan Valley is described in greater detail in Drennan (1978:1-7) as are
the issues involved in coming to an understanding of it.
The several chapters in this volume are reports on various portions
of the studies we have carried out during a number of field seasons. These
reports vary considerably in nature. Some are final reports of discrete
segments of our work, while others are preliminary reports on more recent
seasons. At this writing, then, we stand in the middle of the project.
Some parts of the project have been completed, and the results are presented
here. Fieldwork for other parts of the project has been completed but
analysis of data has only begun; these parts are described in preliminary
form, as has been done previously (Drennan, ed., 1977 and Drennan 1978), so
that their immediate results may be made available as soon as possible.
And still more fieldwork is planned for several parts of the project.
The chapters are arranged roughly in chronological order, according
to the archeological phases with which they deal. First, because it reaches
farthest back in time, comes a final report by Charles Spencer on surface
survey conducted during 1976 in the area of the Arroyo Lencho Diego at the
downstream end of the Tehuacan Valley (Fig. 1.2). The arroyo is spanned by
1

the impressive irrigation structure called the Purron Dam. This dam was
studied by Woodbury and Neely (1972:82-99), and habitation sites in the ad
jacent region were further described by MacNeish et al. (1972:393-428).
Spencer conducted more intensive surface survey, including detailed mapping
and controlled surface collection, at these habitation sites. His study
spans the entire period during which the dam was in use, from the Early
Santa Marfa phase through the Early Palo Blanco phase (Fig. 1.1). As such
it shows in microcosm the sociopolitical development outlined above in
general terms for the Tehuacan Valley as a whole. Small, apparently egali
tarian villages of the Early Santa Marfa phase gave way to more complex
social forms, culminating during the Early Palo Blanco phase in a hilltop
town (central place for one of the half-dozen polities which existed in
11 11
the valley at this time) before the dam ceased to function and the immediate
area was abandoned. Because of the evidence available from the dam, a
unique data set for its time period in Mesoamerica, Spencer is able to
study in unprecedented detail the relationship between this sociopolitical
development and the development of the system of irrigated agriculture
which sustained it. He can thus offer some unusually well-documented

conclusions concerning this much-discussed relationship.
Chapter 3 relates to Chapter 2, since it is a detailed study of the
evidence for ceramic production at the Early Palo Blanco hilltop town in
the Arroyo Lencho Diego survey area. The contribution of this study by
Elsa Redmond is twofold. First, it provides fundamental information con
cerning the organization of production in this area during the Early Palo
Blanco phase. Such information contributes materially to Spencer•s study
in Chapter 2 and to our understanding of sociopolitical development in the
Tehuacan Valley in general. Second, it outlines the kind of evidence for
ceramic production available for this period in Mesoamerica. Despite the
heavy reliance of archeologists on the study of ceramics and the number of
implicit assumptions we make concerning the organization of production of
ceramics, actual archeological evidence bearing upon this organization is
extremely scarce for Mesoamerica. Mesoamericanists have not been unaware
of the problems created by this scarcity of evidence, as the attention to
ethnographic studies of pottery manufacture shows. But concrete archeo
logical data on pottery manufacture have been difficult to locate. An
occasional feature from a later time period has been interpreted as a
ceramic kiln (see, for example, Winter and Payne 1976), but the direct
artifactual evidence of pottery manufacture has received almost no atten
tion. As Redmond shows, Mesoamericanists need not nurse a concealed envy
of colleagues who work in regions such as the Near East where "kiln
wasters" are well known, although we may have to hide some embarrassment
at our failure up to now to make more of evidence that is, under some cir
cumstances at least, available in Mesoamerica.
Chapter 4 is out of place chronologically in that it deals with an
earlier phase than the most recent developments discussed in Chapters 2
and 3. John Alden presents a final report on systematic surface survey
conducted in 1975 at Quachilco, the Late Santa Mar1a phase site repre
senting the earliest "town" in the Tehuacan Valley (see above). It is
located in the center of a broad level expanse of alluvial farmland in
the central section of the valley (site 218 in Fig. 1.2). Here are found
the earliest indications of the more centralized kind of sociopolitical
organization which characterized the Classic period. On the one hand,
Alden•s survey served as a guide for the 1977 excavations at Quachilco
(Drennan 1978), suggesting notions about the organization of the site to
be pursued by collecting data through excavation. On the other hand,
the data from the surface collections complement the excavation data by
providing a view of the site more extensive and complete than one at
tained through limited excavation at a large site, although subject to all
the problems inherent in dealing with material not in primary context.
Beginning in Chapter 5 we turn to preliminary reports with a des
cription of 1978 excavations at Cuayucatepec (site 281 in Fig. 1.2).
Founded during the Early Palo Blanco phase and occupied into the Late
Palo Blanco phase, Cuayucatepec represents the period during which the
pattern of "town" organization was replicated throughout the Tehuacan
Valley. Cuayucatepec was a second generation central place, one of the
half-dozen which, like the hilltop town in the Lencho Diego survey area,
succeeded Quachilco. The excavations here were explicitly intended to
